The object of this invention is to provide an improved construction offaucet or similar device of the reciprocable piston type in which thecasing is provided with a chamber around the casing in the region wherethe piston is in fluidpassage closing position whereby the latter membercan, if desired, be made as one head and the pressure thereon equalized.A further object of the invention is to provide an im- .provedconstruction of such piston valve that it can be compressed by turningthe stem as the body thereof becomes worn or to stop leaks if theyoccur. Other objects will appear from the disclosure herein.

The invention is embodied in the preferred examples herein shown anddescribed, the features of novelty being pointed out in the claims.

In the accompanying drawing- Figure 1 is a central vertical section withparts in full of a faucet according to the invention.

Fig. 2 is a. horizontal section on the line 11-11 Fig. 1.

Fig. 3 is a detail view of the piston stem employed in Fig 1.

Fig. 4 is a vertical section like Fig. 1 illustrating a modification ofthe means for carrying the pistonv and whereby the piston can beadjusted for compression or relaxation.

Referring first to the views Figs. 1-3, the character ill designates thecasing which has an intake II and a discharge l2. In the cylindricalwall of the case above the discharge is formed an annular projectiondefining an annular passage l3, said passage having an inlet I to whichleads a passage l5 so that water or other fluid flowing into the inletmust pass through the passage M to the exit at the discharge i2.

It will be observed that the lower end of the cylindrical casing issubtended by a'wall l5 and that the passage i5 is formed by an addedshell 15 cooperating with said subtending portion and a side of thelower end of the casing.

The character i6 designates the piston which is of cylindrical form tofit in the cylindrical chamber or bore of the casing l0. Said piston ismounted on the lower end of a stem I! (Fig. 3) the latter consisting oftwo parts of different diameters with a shoulder l8 at the junction. Thelower ends of the portions of the stem are each threaded to receive nutsl9 and 20. The packing-23 or body of the piston which, in the presentinstance, is of elastic material, such as rubber, is mounted on the stemportion between two washers 2| and 22 with the nuts I! and 20 pressingagainst them. If desired the body of the piston can be made in two partswith a metal washer 24 between them.

The upper end of the casing i0 is provided with a screw cap 25 that canbe removed at will. Said cap is centrally perforated for the 5 extensiontherethrough of the upper end of the stem. H.

The stem i1 is shown as provided with means. for reciprocating thepiston consisting of a hand lever 26, hollow at its lower side,pivotally and 10 removably connected at 21 with the stem and fulcrumedat 28 to one end of a link 29 that, in turn, is pivotally connected at30 between ears fixedly projecting from the casing I0. By sufficientlyelevating the handled end of the lever 26 from the position shown insaid Fig. 1 the body of the piston can be moved upward to permit flow offluid from the inlet II to the outlet l2, and in this flow it will benoted, that the fluid passes upward to the opening I4 and thence 20downward to the outlet I2 which can continue in an ordinary basinspigot, as shown. When the piston is returned to the down position shownin Fig. l, the pressure of the fluid extends entirely around .the bodyof the piston 25 equalizing the pressure and therefore normallypermitting easy movement of the piston.

By unscrewing the cap 25 and elevating the piston so that the nut I9 isexposed a little above the upper end of the casing a wrench can beapplied to the nut I9 to expand the washer 22 on the packing andtherefore stop a leak; or if the piston be so tight as to render theoperation of the piston difficult the wrench can be applied to said nutiii to relax the expanded condition. In either of these adjustments thepivot member 21 and handle 26 prevent the stem 25 from turning when thewrench is applied.

\ The two adjustments described in the foregoing paragraph can also beefiected by turning the stem l1, while in lowered or closing position,in the proper direction the nut 20 being held from turning by a wall orwalls 32 flxed at the bottom of the piston chamber, said wall contactingparallelly with a facet of the nut 20.

In Fig. 4 there is shown a piston of improved construction that can beadjusted for the purposes set forth in the two foregoing paragraphs. Inthis view the casing part is the same as in Fig. 1, and the pistonconsists of a body member 50 40 of cylindrical form and of such materialas before described having an axial perforation, the ends of which areconical sockets. The said body member is supported by a screw bolt llextended upward through perforated metallic expander 5 members 42 and 43fitting in the aforesaid conical sockets and metallic washers 44 and 45on opposite ends of the body member. The upper protruding threaded endof the bolt 4| is engaged by the internally threaded lower end or thestem 46 proper while the upper end of said stem is adapted to receive anoperating handle 26 such as shown in Fig. 1.

The lower end of the bolt 4| is shown as provided with aIrusto-pyramidal head that engages a similar socket at the bottom of thepiston chamber of easing Ill when thevalve is in closed position toprevent rotation of said bolt. By turning the stem 46 in the properdirection the piston body can be expanded or relaxed by varying thepressure exerted on the upper washer 44 by the lower end of the stem 46,such pressure being communicated to washer by bolt 4i and its head. Withthis construction a leak can be stopped or difllcult reciprocation ofthe piston remedied without cutting off the fluid pressure.

The forms of the parts can be changed without departing from the gist ofthe invention as claimed.

What I claim is:

1. A faucet of the reciprocating piston-type including a casing having acylindrical wall with a lateral outlet port at one end thereof, anannular fluid passage in said wall at one side of said outlet portcommunicating with the interior of the casing, a fluid intake to thecasing at the opposite side of said outlet port, a passagecommunlcatingly connecting said intake with said annular passage, awallof said connecting passage constituting the end of said cylindricalwall between said intake and the outlet port, and a piston-type valve insaid cylindrical wall movable in one direction to close communicationbetween said lateral outlet port and. said annular passage and movablein the opposite direction to 5 open communication between said outletport and said annular passage and thereby establish fluid communicationfrom the intake to said outlet port.

2. A faucet or the reciprocating piston-type 10 including a casinghaving a cylindrical wall with a lateral outlet port at one end thereof,an annular fluid passage in said wall at one side of said outlet portcommunicating with the interior of the casing, an intake to the casingat the oppo- 15 site side of said outlet port, a passage communicatinglyconnecting said intake with said annular passage, a wall of saidconnecting passage constituting the end of said cylindrical wall betweensaid intake and the outlet port, and pis- 20 ton-type valve insaid-cylindrical wall of resilient material movable in one direction toclose communication between said lateral outlet port and said annularpassage, and movable in the opposite direction to open communicationbetween 5 said outlet port and said annular passage and therebyestablish fluid communication from the intake to said outlet port, saidpiston-type valve having a two part adjustable stem and compressionmembers thereon, and means whereby said 30 a stem may be engaged at oneend 01' one of its parts with the aforesaid wall of said connectingpassage and the compression members actuated by turning the other partor said stem.
